EVO LED and Haight Solid State

Been doing a lot of journal hunting, and these 2 brands of lights seem to be doing some very unique things.


At the $300-400 price range;
Haight Solid State PPF-400 (90 watt claimed draw)

Evo70 V3 (60 watt actual draw)


Haight I'm up in the air about, there was a 2009 Haight model put up against a HGL 126x1watt and the HGL walked all over it.... more than double the yield.
I understand that was 2009, and the LED's have become more efficient, new spectrum's have been introduced, and higher wattage LED's are being used.
Does anyone have links to a newer journal that comapres Haight SS, to any other "industry leaders"?



I have yet to see EVO LED's in action, other than a few shots on their webpage. I guess what I'm really wondering is if these "luxury" LED's companies that are taking a different approach are really worth the money? I'm getting mixed results from different parts of the web!


If 90 watts (or 69 watts) is actually on par with the 200-300 watts from HGL, or Advanced, or Pro-Grow etc, it'd be worth it to save the extra power. I love the fact that some companies, like these, are using really high powered LED's like CREE XP-E's.... (not sure what Haight uses, but they're all 6 watts)


I love the design of these LED's too, they're small, light-weight, and just look friggin' awesome. I'm so torn about whether or not it's worth it to buy one of these...

So many LED growers splooge over the equation g's/watt;


I'd like to see a comparison contrasting;
Grams/watt vs. grams/$ spent


Only then can we really see if the efficiency of certain LED's outweighs their high cost, or if the lower efficiency, cheaper LED boards initial cost savings outweigh the cost savings on power usage.

If it does turn out that having the higher efficiency LED's like Haight and EVO produce more yield for the same wattage, how many extra grams would the Haight and EVO have to pull over how many extra grows to actually see the initial cost of the startup equaled out?



I'll explain a bit better, if I can;

Haight 300 watt LED: $749.00

Blackstar 500 (300 watt LED): $539.99
_________________________________
Difference of; $209.01

Let's assume, just for the sake of this example, the Haight produced more yield. How many grows before the initial cost of the Haight is made back up? If there is no difference in yield, it's pointless to even bother with the Haight to begin with.


Now, there's also the idea that less wattage from Haight and EVO is equivalent to more wattage from other companies using less efficient, cheaper LED's.



So, if we looked at it like this;

Haight 180 watt LED: $549.00

Blackstar 500 (300 watt): $539.99
________________________________
Distance of: $9.01

If the yield was the same on these 2 lights, there's no question. Same price, same yield, less draw from the Haight SS LED will save you money almost immediately on your power bill.



If you can get 3g/Watt from your lights but paid $20/watt if doesn't matter how efficient they are, you're getting hosed! As an LED community, we need to figure out how we can get the most grams/watt while spending the least $/watt.

A lot is being assumed in this post, for argument sake and for the benefit of trying to figure out some common ground between radically different LED lighting systems.

Input is always welcome, this thread is not intended to promote of denounce any LED company. It is only an effort to better understand the differences between the systems on the market, and how companies are progressing the design of LED's.

There's a guy here that uses that 90 hss and got ok results for the actual watts used. I don't know much about the evo leds to speak on them yet.

My gut is telling me that there's no way the 90w hss will perform as well as a proven 180-200w panel from glh or advanced. But I could be totally wrong. the same for the evos...I'm not sure but id love to see some tests

the HSS PPF-400 is the older one, now its PPF-400Rv2... I will be using one soon, I ll let you know how that goes. I don't think that you should let 200$ difference influence your choice,... I mean you are buying the light for 50000hours, what'ss 200$ after so many crop?

EDIT: speaking of the devil, I just got the HSS today! I will post pictures soon, so far the nicest LED I have, very well built, very light... I was surprise to see a control for low/high intensity because I hadnt seen this feature on their website.

Nice, I wasn't aware they came out with the new r2 models. Interested in seeing how they perform!

Hey endur0, seems like youve been buying a lot of leds recently, which ones do you have again?

My mistake, I forgot the v2... I believe the prices are properly reflected however!

Thanks for catching that!


I don't think the $200 difference should be the sole deciding factor, but realistically cost is a limiting factor for lots of people.

It's be awesome if everyone could afford a BMW, but they can't; so KIA exists

I have :
90W quadband UFO
90W BLUE 5th generation UFO
100W Advanced Extreme Diamond
Blackstar 240
Fero 4G 180
HSS FPP-400 Rv2

They are all pretty much the smallest unit of each brand, I am not using all of them at the moment. As soon as the FERO proves itself, I will put the 90W UFO quadband to help finish the 2 plants in the dresser, I will wait to see the buds getting significantly bigger before I do so...The diamon is currently with the 400s, the 90W blue and the HSS are over some clones that are trying to make it in life. I am thinking of putting the Blackstar in the room with the HIDs as well but I don't really know how to set it!! ( the 2 400s alone are covering most of the canopy with their hood) by the way, I had to pay 50$ more to have the Rv2 instead of the older model...

There you go! the pics HSS8 I believe, you see what looks like a scratch or something on the glass of the light, but it's mylar reflecting... And because most of you probably don't follow my journal, here is a bonus, a black ladybug! It was drowning in my bucket of waste water when I saved it last night hehe.

I don't like the looks of the EVO and Haight LED's.. There's no proper heat management, which is crucial to optimize efficiency (light output) and lifetime of the LED. Sorry to quote KNNA again, but he did have a very good post on heat management. http://www.gardenscure.com/420/lighting/117772-how-build-your-diy-led-array-2.html#post1247178
Here he talks about the amount of exposed aluminum needed to cool the LED's. Without any active cooling (fans'n'shit) he says a light needs roughly 150 sq cm per watt. or 21 sq inches.

As I do not see any active cooling on the Haight LED, it would need roughly 13500 sq cm (90*150 sq cm) to keep optimal efficiency. This would require a flat exposed aluminum surface which is 90 x 75 cm (taking in to account that both sides are exposed, and that is not the case with the Haight light)
So basically what I'm saying is, the Haight light might seems nice and small, but unfortunately this is not good in this situation.

P.S. This might explain their extremely short warranty (compared to how long life expectancy LED's usually have)

I use the HSS PPF400 older model and it works decently. I do keep a fan blowing over it while the light is on, this helps to keep the temp down as the back does get quite hot without it. Last grow I got 11g of smokable bud from two plants each about 12" tall in 8" round pots (trial run with it in an aquarium stand haha). I'm using it again to do a scrog and going for 1gpw from a 26"x20" area. Their newer versions seem to be better for growing as they use a mix of 3w reds with a narrower lens instead of the wide angle 6w reds from the older models. I found about 9" to be ideal in veg and about 6" in flower. This does give the light a limited footprint, but for a 90w light the footprint isn't all that small.

if you want to see EVO leds in action, you should go on cannabiscafe (spanish, but there is a page where you can select "languaje" and put in "ingleses" sorry for my spanish mistakes).

Or you can watch Mr X Grow, at icmag (He said he pulled around 300g per Sq Meter, 2sq Meter in total using 4 evo 90 (70ish each actual draw power)
https://www.icmag.com/ic/showthread.php?t=215147

About the solid state, there is someone on bubbleponics but I havent seen it and trying to find the grow (I will update you on the subject)
But there is an other grow here: http://www.ugcf.info/forum/index.php in the growing section (you'll need to register)

PS: THE SPANISH, SEEM TO BE AHEAD WITH LEDS TECHNOLOGY, BOTH DIY AND COMMERCIAL... THEY ARE ALSO VERY "PERMITTING" WITH GROWING ITS IN THEIR BLOOD SMOKING CANNABIS.. ALSO THE HIGH TEMPERATURES THEY HAVE, THUS THEIR DEVELOPMENTS IN LEDS

20$/watt

fuck thats spendy

how do you come to this number

that link on icmag is impressive i wish that it was more apparent the brands he choose to use

what is the actual draw power of my HSS? I sure hope I get more than 11g out of it! 400$ light! The clones that werent in so good shape are responding well to the light already, the plants are actually green under it, it gives off a nice daylight type of light.... but 11g out of what 60-70 watts ... what happen to the 1.5gpw everybody is suppose to get with LEDs!!! The plants under my HIDs are doing really well, hopefully I get a good harvest there because I am losing hope with my LEDs!!

I'm not sure what the power draw is, still haven't had a chance to test it. Mine says on the label that the typical power draw is 90w and that the maximum is 150w, so I actually wonder if the diodes are 10w max and the driver is pushing them at 6w each? Also where in the world did you pay $400 for it? I got mine for about $270 plus shipping.

Don't worry, you should get a lot more than 11g out of it, especially with the newer model. I had a lot of problems with my last grow using it: no reflective coverings on walls, space it was lighting was 11"x32", flowered clones at just over 6" tall with no training, low yield strain to start with, and harvested about 1.5 weeks early. As long as you don't screw up everything like I did you should be able to pull at least .5 gpw with it on your first run IMO. From there the number should only go up, there's a learning curve with LEDs just like anything else in life. If you don't get a stellar yield the first time, analyze what went good or bad and improve on those things.

Just an ambiguous number thrown out there to illustrate a point. I don't actually know of any LED companies that are that expensive.

Any other info on evo leds?

You got the 90w Haight for $270+shipping? Where?? It's $299.99 for the old model on Haight's site...

I got mine from gianthydro.com. Right now they have it listed for $259 with free shipping for the older model. Greners has it for slightly more, and both have the ppf-800 v1 (180w) for $420 plus shipping. They also both have kessils available for a pretty good discount.

I was gonna say that among the low power draw lights, kessil is good. I really want to get a bunch for a new grow at some point. They cover a good 2x2 for the 90w and have good penetration. KawiZZR, you still shouldn't have cut them. They were looking so good. Btw speaking of the HSS, are the 1600's any good? Would they be better than a 500w BS?
